ABSTRACT:
An apparatus for introducing a material into a kiln using low pressure air injection. In a preferred embodiment, that apparatus has a movable vessel that is movable between a collection position and a discharge position. The vessel has an open top and an open base. The open base supports a discharge gate that is movable between an open position and a closed position. In the closed position, the discharge gate prevents discharge of the material from the vessel while the vessel is moving from the collection position to the discharge position. An actuable vessel cover is adapted to cover the open top of the vessel when the vessel is at the discharge position. A low pressure air injection assembly, supported by the vessel cover, injects air into the vessel to force discharge of the material through the open base, the discharge gate and into the kiln.
